Arc'teryx designed the Spear 20 Daypack for exploring cobblestone streets overseas, whipping through traffic on your bike, or taking to a trail outside of town. Simple, tough, and technical enough for daylong outdoor pursuits, this pack was designed with a RollTop closure and aluminum stays to carry so comfortably that you'll forget there's a weight on your shoulders at all, and even has a hydration-compatible sleeve to help keep your insides lubed up during a day on the go.
